## Overview

This Flask application supports account registration and login, session-based authentication, role-protected pages, and administrator CRUD for users and roles. The main workflow runs through the route handlers: forms validate submissions, user and role models provide identity and authorization data, and successful requests render pages or redirect. Admin access is separately enforced by the Flask-Admin views. The README also documents schema migrations and deployment database configuration; these are not expanded into operational components here because the sampled runtime code does not show their detailed flow.

Main entry points: [`app/routes.py`](https://github.com/drun16/flask_rbac_project/blob/main/app/routes.py) (Web routes), [`app/models.py`](https://github.com/drun16/flask_rbac_project/blob/main/app/models.py) (User and role models), [`app/admin.py`](https://github.com/drun16/flask_rbac_project/blob/main/app/admin.py) (Admin interface), [`app.db`](https://github.com/drun16/flask_rbac_project/blob/main/app.db) (Application database)
